Answer:

Fossils are the remains of ancient plants and animals that were buried millions of years back. These are found to be embedded in the sedimentary types of rocks. The earliest known direct fossils are not obtained in the present day, but the imprints of these fossils are explored in many of the places. These were the ancient micro-fossils such as bacterias, cyanobacteria that existed about 3.5 billion years back.

Some of the direct evidence of fossils are obtained from the rocks in the western part of Australia and the southwestern part of Greenland.

Thus, the imprints of these fossils are found in many rocks at different places, and this suggests the existence of life during that particular time frame.

AVprozaik [17]

Answer:

In Labrador dogs, black coat is dominant to chocolate, normal vision is dominant to progressive retinal atrophy (PRA), and normal hip joint is dominant to hip dysplasia. All these genes assort independently. Two dogs that are heterozygous for alleles of all three genes are crossed. Using rules of probability (not a Punnett square), what is the chance that the first pup born to these dogs will be chocolate, have normal vision, and have normal hip joints?

BbVvHh x BbVvHh= BBVVHH, BbVvHh, BbVvHh, bbvvhh

Bb= black coat dominant

Vv= Normal vision dominant

Hh= Normal hip join dominant

probability of having a first born of these dogs will be chocolate, have normal vision and have normal hip joint is 0

Explanation:

As the punette square gives 3:1 phenotype having three black coat, normal vision and normal hip joint and one chocolate, progressive retina altropy and hip dysplasia

In an experiment, what is the factor that is tested?

Marta_Voda [28]

In an experiment the HYPOTHESIS is tested. The hypothesis is the assumption, that you make about something. Example would be, you believe (hypothesize) that the baking soda will react faster in vinegar than in water. You then test it out (or preform and experiment) to see if your hypothesis is correct or wrong.
